• Visual C++ Autogenerated copy constructors and equals operators

  Hi everyone, Anyone know how to inhibit the compiler's autogeneration of copy constructors and equals operators for classes other than defining your own I have a template queue class for which cloning is not really a valid operation, and as such some of it's nested types are not suitable for auto-generated copy constructors/operators. Because of this, when I compile some code that uses the outer template class, I get compiler errors such as: error C2678: binary '=' : no operator found which takes a left-hand operand of type 'volatile T<itemtype>::NestedType' (or there is no acceptable conversion) When I double-click on the error, the editor simply goes to the end of the class declaration that has declared a member o ...Show All

• Visual Studio 2008 (Pre-release) Page navigation and de-serialization bug?

  I think I stumbled onto a bug. I'm building a navigation-based application using WPF. In it, I have a Page with a number of controls on it, mostly TextBlocks, TextBoxes and ComboBoxes. I also have a UserControl in there, which itself has a number of the same types of controls in it. The contents of both the Page and the UserControl are defined in XAML. On the Page, I have a TextBox (say TextBox1) with some text in it. In the UserControl, there is a TextBlock (say TextBlock1) with some text in it. The values of both controls are defined in XAML. Here's the problem: If I navigate away from the page, and then return to it through the back button, the value of TextBox1 (in the Page) ends up in TextBlock1 (in the UserControl)! Here are a few t ...Show All
